The invention discloses an engine residual heat recovery system for an equipment electromechanical coupling supercharger. The electromechanical coupling supercharger, a supercharger controller, a high-voltage battery, an ISG (Integrated Starter and Generator) and an ISG controller are connected in series to a same high-voltage bus, by means of control of an ECU (Electronic Control Unit), electricenergy is made to flow between all components through the high-voltage bus, the electromechanical coupling supercharger comprises a turbine supercharger and a motor-generator integrated to the turbinesupercharger, the turbine supercharger comprises a turbine machine and an air compressor, the turbine machine is connected to an air exhaust pipe of an engine, the air compressor conveys fresh air after compression to an air inlet total pipe of the engine through an intercooler in working, and the ISG is connected with the engine. Compared with the prior art, the engine residual heat recovery system for the equipment elec
